how g is mined g mining process world g councilyet mining the ore is just one stage in a long and complex g mining process. long before any g can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly. the g trade of ancient ampmedieval west africa world the trade of g in west africa goes back to antiquity with one of the earliest examples being the voyage of the carthaginian explorer hanno in the 5th century bce. the celebrated mariner sailed out of the mediterraneanand, turning south, stopped off at the mouth of the senegal river before sailing on and perhaps even reaching as far the bay of guinea. hanno was followed by other countrymen, and commercial relations were established with the locals. thus, west african g found its way from the trading post/island of cerne (unidentified but on the atlantic coast) northwards to the ancient mediterranean cultures for the first time. the 5thcentury bce greek historian herodotus describes in his historiesthat g was traded on the west african coast using a silent and cautious method of barter perhaps understandable given the language barrier and mutual fear between unfamiliar peoples: the romans were also interested in what africas interior had to offer and they employed crosss see full list on ancient.eu the islamic north african empires of the medieval period had an insatiable demand for g because it was needed not only for making precious manufactured goods (e.g. jewellery, vessels, embroidered clothing and illuminated manuscripts) but also to mint coinage to pay armies. traditional islamic teachings might have forbidden men to wear g but a few coins in ones pocket was especially useful for siers of no fixed abode. the islamic sensitivity to the metal is also evidenced by the fact that jewellery work was most often done by jewish craftsmen once it reached the north african cities. in addition, g was needed to pay the growing number of spanish, italian, and other european merchants who traded in the southern mediterranean. much of that g then ended up as coinage in such places as castille, genoa, florence, and venice from the late 13th century ce. the great problem for the north african states was that to obtain the g of west africa they had to first cross the sa see full list on ancient.eu one of the first subsaharan states in west africa to gain attention in the wider medieval world was the ghana empire (613th century ce), located in modernday southern mauritania and mali. the empire became famous for its g, earning itself the nickname the land of g. the metal came from gfields in ghiyaru, galam, and bure on the upper niger river (modern guinea), and via traders who brought it from the gfields of bambuk at the meeting of the falem and senegal rivers. g was largely found in alluvial deposits where it was easily panned to find g dust and grains or in veins in relatively shallow mines. mine shafts were typically only a few metres deep and produced a mere 2.5 to 5 grammes of g each so thousands of shafts were dug in a single gbearing area. most g was not refined although its purity was high anyway but was melted down to cast it into convenient bars for transportation. the most common commodity that g was used to purchase was salt, see full list on ancient.eu the mali empire (12401645 ce) gained access to new gfields on the black volta (modernday burkina faso) and in the akan forest (modernday ghana), and its kings became even wealthier than their regional predecessors in the ghana empire. mali probably did not directly control the southern gbearing regions but, rather, extracted from them the precious metal as tribute. malis most famous ruler was mansa musa i (13121337 ce). having converted to islam, mansa musa duly went off on a pilgrimage to mecca in 1324 ce. when he stopped off at cairo en route in july of that , the kings wealth in g caused an absolute sensation. in some accounts, mansa musas caravan included 100 camels which carried 135 kilos (300 pounds) of g dust while 500 slaves each brandished a 2.7 kilo (6 pounds) g staff. after straight away giving 50,000 g dinars to the sultan of egypt merely as a gesture of goodwill between two great rulers, mansa musa would subsequently give away so much g see full list on ancient.eu the mali empires successor as the most powerful state in west africa was the songhai empire (c. 1460 c. 1591 ce). the songhai, continuing the triedandtested wealth accumulation method of trading subsaharan commodities and extracting tribute from conquered tribes, established the largest and richest empire yet seen in west africa. however, things took a turn for the worse in 1471 ce when a portuguese fleet, sponsored by the lisbon merchant fenão gomes, sailed around the atlantic coast of africa and established a trading presence near the g fields of southern west africa. in addition, other kingdoms arose to compete with the songhai for a share of the g trade, especially to the west the bornu empire (13961893 ce) near lake chad, hausaland (c. 1400 c. 1800 ce) between the niger river and lake chad, and, in the south, the kingdom of benin(1319th century ce) in modernday nigeria. see full list on ancient.eu the portuguese ships which now regularly sailed down the atlantic coast of africa offered west african forest peoples a middlemanfree alternative to the transsaharan caravan routes. the portuguese were especially keen to obtain g because they needed it to pay merchants in asia who were not so keen on exchanging goods in kind. there was still, though, plenty of g travelling northwards through the songhai empire and onto north africa but the african monopoly of the trade was now at an end. in the 15th century ce, west africa was producing 10% of the worlds g. on average, some 400550 kilos a were being handled by the portuguese alone in the 1500s ce. not surprisingly, european powers began to show an interest, such as england, france, denmark, sweden, and the netherlands. fortifications were built, not to defend the europeans from the native africans but from each other. in short, it seemed that west africa had exactly what everyone else most wanted: slaves and g. see full list on ancient.eu west african g continued to be exploited after the medieval period as european powers competed for whatever they considered of value in the continent. the g extracted from west africa, though, was dwarfed by that extracted from the new world, the inca civilization and aztec civilization, in particular. european powers were also now far more interested in acquiring slaves than g, many of them destined to work in the plantations of the americas. west africa was not finished with g, though, and kept producing it using much the same simple methods as had always been employed. the modern state of ghana, formerly known as the g coast, gained independence from britain in 1961 ce, and the introduction of new mining technology meant that it once more played a major role in the international g markets. for a while, ghana ranked 5th in the world in terms of annual g production. already in the mid19th century ce, though, attention had turned elsewhere for new sources of th see
